Type R622-LBW Regulator
Introduction
This installation sheet covers the installation, startup, and
adjustment procedures for Type R622-LBW pressure reducing
regulator. These regulators have internal relief to help
minimize overpressurization of the downstream system.
Specications
(1)
Maximum Allowable Inlet Pressure
10 psig (0,69 bar)
Maximum Emergency Outlet Pressure
20 psig (1,4 bar)
Maximum Operating to Avoid Internal Part Damage
3 psid (0,21 bar d) above outlet pressure setting
Outlet Pressure Ranges
13 to 20-inches w.c. (32 to 50 mbar)
Material Temperature Capabilities
-40° to 160°F (-40° to 71°C)
Installation
!
WARNING
Personal injury, equipment damage, or leakage
due to escaping accumulated gas or bursting
of pressure-containing parts may result if this
regulator is overpressured or is installed where
service conditions could exceed the limits
given in the Specications. To avoid such
injury or damage, provide pressure-relieving
or pressure-limiting devices to prevent service
conditions from exceeding those limits. Also,
physical damage to the regulator can result
in personal injury or property damage due
to escaping gas. To avoid such injury and
damage, install the regulator in a safe location.
1. Only personnel qualied through training and
experience should install, operate, and maintain a
regulator. Before installing, check for damage
which may have occurred in shipment. Also
check the regulator and pipeline for debris.
2. The Type R622-LBW may be installed in any position.
Apply a good grade of pipe compound to the male
threads of the pipe (being sure not to apply pipe
compound to ow path of the pipe) and install the
regulator so that the ow is in the direction of the arrow
cast on the body. Use approved piping procedures
when installing the regulator.
!
WARNING
A regulator may vent some gas to the
atmosphere. In hazardous or ammable gas
service, vented gas may accumulate, and
cause personal injury, death, or property
damage due to re or explosion. Vent a
regulator in hazardous gas service to a
remote, safe location away from air intakes
or any hazardous location. The vent line or
stack opening must be protected against
condensation or clogging. Under enclosed
conditions, the vent should be piped away
from the regulator to a safe location.
3. On outdoor installations, regulators installed with
vents in positions other than vertically down require
additional vent protection from the elements.
4. Regulator operation within ratings does not preclude
the possibility of damage from debris in the lines or
from external sources. A regulator should be
inspected for damage periodically and after any
overpressure condition.
5. To adjust the regulator, monitor downstream
pressure with a gauge during the adjustment
procedure. To increase the outlet pressure,
the adjustment screw (key 23, Figure 1) must
be turned clockwise. This requires removal
of the closing cap (key 31, Figure 1). To reduce
the outlet pressure setting, turn the adjusting
screw counterclockwise. Do not adjust the
spring above the limit stamped on the regulator.
1. The pressure/temperature limits in this installation sheet, and any applicable code or standard limitations, should not be exceeded.
